Interesting. Could you give some examples?

And indeed, I've done an addition instead of a subtraction in the bytecode, making the computation of blue overshoot values incorrect. This is fixed now in the git repository; please update and regenerate your test files!

More testers and more eyes would be good too. Indeed!

Well, please report whether the current git gives better results.
